close

public void close()

requestPublicIP

public void requestPublicIP()

STUN : Request real Public IP

requestPublicIP

public void requestPublicIP(boolean change_ip,
 boolean change_port)

STUN : Request real Public IP from a different IP and or Port

requestAlloc

public void requestAlloc(boolean evenPort,
 byte[] token)

TURN : Request a UDP data channel. Token is optional, used if last request was for even port (to alloc the odd port).

requestBind

 String host,
 int port)

TURN : Bind to host:port (also a keep alive)

Parameters:

channel - : 0x4000 thru 0x7ffe (you pick one by random I guess)

doTest

public static STUN.NAT doTest(int port,
 String host1,
 String host2)

Performs a quick test to determine your firewall type.
